Specification of Letters Patent.

BERLIN, GERMANY, ASSIGNOR TO MERGENTI-IALER-LI1\TOTYPE COMPANY, A CORPORATION OF NEW YORK.

Application filed April 11, 1914. Serial No. 831,109.

T all whom it may concern Be it knownthat I, KARL ROGER, a subject of the German'Emperor, residing at 33 Teltowerstrasse, Berlin, in the Empire of Germany, have invented new and useful Imlarly in matrix or type die composing and line casting machines, in which the magazlneswlth their matrices are removed from the rear of the machine, a bar is pushed n at the upper end of the magazine before it is rocked rearward, or another locking de-' vice is provided to prevent the matrices from falling out. Inlmagazine channels containing only a small number of matrices which does-not completely fill those chanthe trade mark Linotype. F V s Figure 1 is a side elevatlon ofthe part nels,' the matrices whichformerly were in the lower part of the magazine will slide into the upper part, "striking against the locking device when the magazine is tilted, and vice versa when the magazine is put again into the machine they will strike against the escapement devices atthe lower end. 7 The matrices thereby become damaged, as they receive rather a sharp blow, and the invention has for'its object to remedy this difiiculty.

The drawing showsa constructionalform of the invention when applied to a machine of the Mergenthaler system known under of the machine in question and of the magazine; Fig. 2 isa part of Fig; l on an enlarged scale. Fig. 3 is a plan of a part of Fig. 1, Fig. 4: shows a somewhat altered constructional form of the invention. Figs. 5

'and 6 are sectional views showing the-magazine in different positions and Fig. 7 a

detail view.

The magazine a with its supporting frame 7), can be rocked to the rear about a pivot 0 in the machine frame (Z, so as to enable the magazine to be taken out of the machine rearwardly. Before the magazine is rocked down, its upper. end islocked in the known manner, not shown in the drawing, n order to prevent the matrices from -fal'l1ng out.

In'order to'prevent thejmatrices from shifting to and fro in channels which are not quite full, further locking devices are pro vided, which, according to the drawing, consist for each channel of a two-armed lever e, whichon its free end carries a locking pawl f, entering a hole in the bottom plate of the magazine, to lock the matrices. The looking pawl f is drawn out of the magazine by a spring 9, which thuskeeps it in an inoperative position. The movement of the pawl f into and out of the magazine, is effected by an eccentric or cam h engaging one arm of the lever e, and either rocking the latter in sucha manner that the'locking pawl f enters the magazine, or allowing the spring 9 Patented June 8, 1915.

to act upon it to withdraw the pawl from the magazine. The cam 71. is rotated two arms 2' and 71 which are connected to its outer end and'are adapted to cooperate with a fixed stud on the machine'frame as the magazine is rocked downward and upward,

the arrangement being such that during the downward movement of the magazine, the cam 71. will be turned to project the pawls f into the magazine channels, and during the upward movement of the magazine the cam will be rotated in the opposite direction to allow the pawls to be withdrawn from the magazine by the springs-g. The operation,

is as follows: When the magazine is in its normal position as seen in Fig.1 1, the arms 5 and i occupy the position shown in that.

figu re.' As the magazine is rocked downward .for removal, the upper arm i is brought into engagement with the stud is on the framework, see Fig. 5, and the continued downward movement of the maga zine causes the arm to be shifted clockwise to the position shown in Fig. 6, thisshifting of. thearm turning the cam h and eflecting the projection of the pawls f intothe. magazine channels in the manner just described.

When the new magazine has been substituted in the machineythe arms 2' and 2' occupy the position shown iii-Fig. 6, and

whenitis rockedupward to its normal position, the lower arm i is' brought into engagemen'twith the stud 7c. and is thereby shifted counter-clockwise to the position shown in Fig. 5, this movement ofthe'arm' turning the cam it back to its original position so as to allow the springs g to withdrawthe pawls from the magazine channels. It will be understood of course that this arrangement is merely shown by way of ex- 116 ample and in preferred form, but obviously other arrangements may be provided to secure the same results, the only requirement being that the locking of the matrices in the magazine be effected at some stage in the removal of the magazine, whether during the initial stage, as shown herein, or during a subsequent stage.

In the constructional form according to Figs. tand 7, a wedge member mis proand thus causes them to project the pawls f .into the magazine channels or allows them zo'under the action of the springs g to withdraw the pawls from the channels, according to the direction of movement of the wedge member. "The movement of the wedge may be effected in: any desired 'manner,.but Iprefer to employ the means shown in Fig.7 ,wherein a curved plate 0 is fixed to the machine frame and isarranged inposition to engage a notch n in one edge of the e wedge', the eii'ectbeing that as the magazine is swungupward and downward, the plate will engage in the notch and shift the wedge positively in opposite directions either to project the pawls finto the matrix channels or allow them to be withdrawn therefrom by the springs g accordingto the direction of movement of the magazine. In the drawing,-only one locking device 0, f, for each magazine channel is shown. Generally one device in the; center of the magazine will be sufficient, but frequently two.- such locking devices may. have to be arranged each at a distance of'one-third of the length of the magazine from the top and bottom of the M latter. I v

,Having thus describedmy invention what I claim and desire to secure by Letters Patent ofthe United States is as follows '1.- Means for preventing matrices or type dies moving in the channels of their. magazines while the" latter are being changed, comprising a locking device for each channel adapted to engage within it and-means adapted to put the device into locking position as the magazine is moved fromi its 5 working positionin the machine and to put it out of. that position as the magazine is moved intoworking position inthe machine.

2 The combination with a channel of a magazine containing matrices or typediesandmovable out of orinto its machine, of a pawl adapted to engage within the channel and pivoted on a lever fulcrumed on the outsideof the magazine, a spring urging V the pawl out of locking position in the chanel, and means" adapted to put the pawl into locking position as the magazine is moved from its working position in the machine and to allow the spring to put it out of locking position as the magazine is moved into working position in the rmachine.

8. The combination witha channel of a magazine, of a lever fulcrumed thereon,'a".

pawl carried by one end of tlie lever and working through the respective side of the magazine, a spring for withdrawing the pawlfrom the-channel, an eccentric on the" magazine and engaging with the lever for pro ecting. the pawl into the channel, two" arms radiating from the eccentric in differ ent directions, and a projection adapted by being supported independently of the magazine, to rock the arms and reverse the positicnlof the pawl during the movement of themagazine from or to its working position in the machine. v 7
